Make sure you use the same JVM and classpath to run the server and WLST. If you use a different JVM or classpath, the server and WLST will have different versions of classes and will not be able to talk.

Thanks for the reply. I have resolved this problem by removing my environment settings and running setWLSEnv.cmd which available in Weblogic.
